I'm looking to build a system around an Athlon 64 2800 and a Chaintech VNF-250. I'd like to start with 512MB of RAM but have the freedom to easily add another half a gig later. I'm not planning to overclock. Which RAM would you recommend? Chaintech's site has a broken link to the compatibility guide for this mobo and the guide for their ZNF mobo is rather cryptic.
